I have to agree with hammmerhead on this. I think you should have jumped at the refund - 10% deal and been done with this. You could have chalked that up as stupid tax and already been cruising around on your new Turf Tiger diesel by now. I doubt that deal is still on the table now though, since that bridge has probably been burned. I figure the absolute best you can hope for now is that Bad Boy will swap out mowers with you or fix what ales yours. If you want to pursue through an attorney and/or the courts, you're probably looking at least half the cost of the mower in fees.
